I bough some college books on Amazon.com on a Friday, chose FedEx 1-2 day shipping so i would get the books on Monday so i would have the books for Tuesday classes. Monday came, i even woke up earlier so i wouldn't miss the FedEx guy. I hear a knock on my door, i open up and it's the neighboors from upstairs, with a FedEx door tag. I went online and checked the my package tracking, and i see that a delivery was attempted. I was at my house all day, never heard the doorbell, nothing.
